The Week of Bad Fans - 2 Macs, 2 Bad Fans ... Wow :)

I own two Macs the Original Core Duo 17" Macbook Pro and a Original MBA (which is a brand new machine a few months of being out of the box)

A few days ago the MBP started sounding like a drill was going on inside the machine. Extremely loud and really sounding like a drill. - Figured out it was a bad fan.

Then today my brand new MBA sounded like the fan was trying to start up and simply doesn't start up - sorta like a bad hard drive trying to mount.

The MBA is still not a problem using it when I'm listening to music or a movie simply because the sound covers up the sound and the temps are really not that bad right now sitting at 57 Celcius doing web and iTunes usage.

But I thought it was so bizarre that in the same week both laptops had fans go crazy.

I actually have not been able to get either machine into the Apple Store because renovations which are ending today! - So tomorrow I will have the fun time of bringing in two Macs with two broken fans - ah - I am just kinda in shock that both my Macs have had their fans bust.

What do you mean a bad thermal sensor? - The temps are reading as they feel and the fan obviously had problems earlier today and not working at all then everything returned to normal - but the MBA did sense the heat but for some reason the fan was stuck not sure how or why but - if it comes back again I'll take a trip to Apple - it still has a full 3 years of Applecare since it is brand new.

Um, it's not a bad thermal sensor, which is what i have
Mine doesn't show a CPU temperature anymore, for like 2 weeks already. However, a bad thermal sensor, or a completely broken one, which is what i have, leads to the fans speeding up to the maximum, and staying there forever. This is pretty irritating and very loud, i don't have applecare anymore, and there aren't any applestore's here. So the only thing i have done as of now, is use SMCfancontrol, and a terminal command to limit my max fan speed to 2.5K. Made it into an app which runs at startup, and i also have other ones for 3K, 4K, and 6K. However, when waking my computer from sleep, the setting doesn't stick, so i have to quickly open the app to limit it again. I now also always have to keep an eye on my cpu usage, so my cpu won't overheat.
